This species is currently known only from the general vicinity of Cerro Yapacana at around 100m asl in Amazonas state, southern Venezuela. The type specimen comes from the non-specific location of "Upper Amazon". It presumably occurs in adjacent Colombia and Brazil, and is likely to occur much more widely.

Habitat and Ecology

It is a large, semi-aquatic species of tropical lowland rainforests. It lives at edge of rivers, where it burrows. It is a viviparous species, probably in water. Its adaptability to secondary habitats is not known, but there is very little human impact within its range.

Population

It is very common in certain localities within its Venezuelan distribution.

Major Threats

It is unlikely to be significantly threatened, but mining activities in the Yapacana area might affect population there.
